NG prepares GEM 63XL rocket boosters to support U.S. Space Force security missions

Northrop Grumman has announced that it is preparing GEM 63XL rocket boosters to support United Launch Alliance’s Vulcan Centaur rocket on the United States Space Force national security missions.

According to a recent corporation news release, Northrop Grumman conducted a validation ground test of an extended length 63-inch-diameter Graphite Epoxy Motor (GEM 63XL) in Promontory.

NG says this variation of the GEM 63 strap-on booster was developed in partnership with United Launch Alliance (ULA) to provide additional lift capability to the Vulcan Centaur rocket

“This new motor optimizes our best-in-class technologies and leverages flight-proven solid rocket propulsion designs to provide our customers with the most reliable product,” said Charlie Precourt, vice president, propulsion systems, Northrop Grumman. “Evolving the original GEM 63 design utilizes our decades of GEM strap-on booster expertise while enhancing capabilities for heavy-lift missions.”

During today’s static test, the motor fired for approximately 90 seconds, producing nearly 449,000 pounds of thrust to validate the performance capability of the motor design. Additionally, this firing verified the motor’s internal insulation, propellant grain, ballistics and nozzle in a hot-conditioned environment.

Northrop Grumman has supplied rocket propulsion to ULA and its heritage companies for a variety of launch vehicles since 1964. The GEM family of strap-on motors was developed starting in the early 1980s with the GEM 40 to support the Delta II launch vehicle. The company then followed with the GEM 46 for the Delta II Heavy, and the GEM 60, which flew 86 motors over 26 Delta IV launches before retiring in 2019. The first GEM 63 motors supported ULA’s Atlas V rocket in November 2020.
